Abstract: A process of forming an image of toner on a latent magnetic image in a magnetic member followed by direct transfer to and coalescence on a surface to form a resist is disclosed. The surface portion not protected by the transferred resist toner image is then permanently modified by etching or plating. Chemically milled shapes are prepared as well as printed circuits and printing plates. The printed circuits may be formed by (1) etching away areas of a metal surface not protected by the resist, (2) electroless plating on areas not protected by the resist or (3) electroplating areas of a metal surface not protected by the resist, removing the resist, and in the case of (2) and (3), etching away the metal previously covered by the resist. An especially useful toner which forms a resist composition comprises a binder of thermoplastic resin and plasticizer and magnetic material present in the binder, compounded to have a tack transfer temperature of no greater than 110.degree. C.

Abstract: A lithographic printing process wherein an illuminated image on a document is scanned in a series of parallel sweeps with a photocell, applying an electric wave signal to a magnetic recording head with the amplitude of said signal determined by the output of the photocell and a function of the optical density of the image being scanned. The magnetic head has a width of from about 0.5 mils to about 5 mils and traverses a magnetic recording medium in a series of aligned parallel paths analogous to those scanned by the photocell to form a latent magnetic image in the magnetic recording medium, which image is a replica of the image being scanned. The horizontal spatial frequency is from about 200 to 1000 cycles/inch. The thus formed latent magnetic image is decorated with an oleophilic magnetic toner. The oleophilic magnetic image is transferred under pressure to a smooth heated lithographic substrate. If necessary, the toner is further heated to effect complete coalescence thereof. The thus formed lithographic printing plate is then used for lithographic printing.

Abstract: A process of forming an image of toner on a latent magnetic image in a magnetic imaging member followed by transfer to a heated transfer member. The transfer member is formed of a backing sheet coated with polyvinyl alcohol. The toner image is then transferred to a substrate using heat and pressure. The backing sheet portion of the transfer member is then stripped away and the polyvinyl alcohol is washed away with water. The surface portion of the substrate not protected by the transferred resist toner image is then permanently modified by etching or plating. Chemically milled shapes are prepared as well as printed circuits and printing plates. The printed circuits may be formed by (1) etching away areas of a metal surface not protected by the resist, (2) electroless plating on areas not protected by the resist or (3) electroplating areas of a metal surface not protected by the resist, removing the resist, and in the case of (2) and (3), etching away the metal previously covered by the resist. An especially useful toner which forms a resist composition comprises a binder of thermoplastic resin and plasticizer and magnetic material present in the binder, compounded to have a tack transfer temperature of no greater than 110.degree.
